Microphone preamplifier - a guarantee of perfect sound

Virtually every home has devices such as a microphone and headphones. The first one is used for recording music, talking with friends on the Internet, singing in karaoke, etc., the latter are needed for listening to songs or talking. Very often even ordinary users are faced with such a problem as a low signal level. Because of this, the microphone does not work well even in karaoke, and the headphones do not let you hear the middle frequencies, and the low and high ones are tapped rather poorly.

Help to solve this problem will help mic preamplifier. Even good quality dynamic microphones are characterized by low sensitivity, so they are not working on modern computers, where sound cards are well received only by electret devices with high sensitivity. Without a preamplifier, we can not do it, because only it can amplify the low signal to the linear level.

Most audio interfaces and mixers already have built-in sound amplifiers, but they do not give the same sound quality as the microphone preamplifier. When choosing this device, you need to be careful, because each unit sounds differently. It's not enough to buy an expensive device with the best features, it should still fit the microphone.

If a professional recording studio can afford to buy several such devices and experiment with sound, then for home use it is often an unprecedented luxury. Therefore, when buying a microphone preamplifier, you need to pay attention to certain of its technical characteristics.

The devices are tube and transistor. There is an opinion that the lamps give the sound velvety and warmth, but this can only be said about the most expensive models. It is necessary to choose a microphone preamplifier with a certain number of input channels. It depends on the purpose for which the device is intended to be used. Ultimately, you need to calculate how many microphones you plan to connect to it at the same time.

In most devices, phantom power is provided , but it is still worth checking whether it is available, otherwise condenser microphones will not work. Also, you need to pay attention to the presence of a low-pass filter, which will cut unnecessary low-frequency noise and remove the effect of barrel and nasal. There are a number of other characteristics, but their choice is a matter of taste for every consumer. To purchase a good microphone preamplifier, you need to listen to it first. After trial application of several models it will be clear which device is better. Note that it is better to check the preamps with the microphone with which it will work in the future, that is, with yours.

If the microphone is responsible for the sound recording quality, then the headphones - for its reproduction. Only a high-quality model will allow you to listen to the work and analyze it. But the problem is that expensive models have more resistance, because of what some frequencies are not audible or are very poorly listened. A preamp for the headphones will allow you to properly adjust their sound. Also, the device allows sound to be output to several headphones at the same time, which is convenient for listening to an audio record by two or three people.
